Our range of Mason colours with over 60 ceramic stains can be used in a wide variety of cost-effective applications. All stains in this revolutionary new colour system contain NO LEAD and can be used as glaze stains or underglaze colours when mixed with a suitable flux, both of which produce strong, vivid colours. See reference notes and Guide to Colour Chart for technical information and suggested percentages of stains. The amount required and the final colour will be dependent upon the glaze or body used and firing temperature. To avoid speckling, thorough mixing and sieving is required.
